This is basically a continuation of the work from #1002 but her for the camlibs directory. The purpose was to replace spaces as a means for indentation with tab characters. Note: there are some files which are still offending the general rule but are (mostly) consistent within themselves. I let them be for the moment. Fixing them would basically replace the whole file. Also: there are still a ton of whitespace related inconsistencies like "x=10" vs "x = 10" or "func(10)" vs "func (10)". This is a whitespace only change (if you include newlines as whitespace).
